Be. it i-mowii that ERNEST lil. ERG11- ERICBL, a eitizen ef the United.Stm/es et America., residing et Detroit., in the ceunty of Wayne andState 01E Mieiiifgzm, have invented` eeztsin new and usefilimprevemeiits in Cariiureters, et' which the fniievvv ing is aspecification, reference being im@ therein to the accompanyingdrffwiugs.

This invention reiatee i0 eau'buretes for internal con'ibustion engines,and especially to eetain features of construction of the liiei supplymive and Hoet chamber by which simplicity, readiness of adjustment, andcertainty ef action in different positions are obtained.

The invention consists iii the matters hereinafter set forth, and morepei'i'iicnlarly pointed mitin the appended claims.

Referring to the drawings, f. igiu'e 1 is e View in iongitudinalsectionthrough s, eau?- buretei which embodies features et the iiivention, Fig.2 is a View in sectimi en. line -m of Fig. 1.

5.11 uuxiiiity duel' 2:33 is formeel im the eene stem 28, its upper endopening into a cup shaped mouthv 34 close to the main duet valve seatand at about the upper level to be maintained in the float chambercontr-nts. Its lower end opens horizont-ally into the float chamber.

A drain' is provided for the tloat chamber, which consists of adepending nipple 35 on the chamber bottom interiorly screw-threaded toreceive a screw-plug 36 which normally closes an oblique duet 37 in thenipple wall.

A vaporizing chamber 38 with deiieetors 39, air inlet valve 40, outletvalve 43, gasolene valve 41 and throttle handle 42, is secured over thefloatchamber7 the mechanism and design being of any approved type, andnot per se forming a part of this invention.

In operation, the float always aets upon the gasolene inlet valve tomaintain a eenst-ant. mean level in the chamber regardless of anytilting or agitation of the carbureter, owing to the universalconnection between the rmgr and lever. The level is readily determinedby inspection of the gage glass, and if not correct, may be quicklyvaried by slackin the shield nut, raising the latter clear o' thenotched bushing, and rotating the shield and the stem, so as to Work thelever nut up and down and thus change the vertical position of' thefloat in the chamber, and thereby shift the level.

The gage glass serves as housing for the fuel valve stein and allows theoperator to instantly detect any lodgment or stickingv of the valve fromimpurities on the valve seat which is visible.

The position ot the cross duet in the tloat chamber prevents theentrance ol Water into the vaporizing chamber. as it is trapped in thelloat chamber below the duet and may be drawn olf through the draincook. Likewise any lighter grade stays at the to the valve receiving asupply ot' substantieilly average and constant density.

The design and ronstruetion may be varied without departing from the.spirit ot' the invention and l do not care to limit myself to anypartirular form or arrangement of parts.
